Ask the Grounding Experts

In this episode, E&S Grounding Solutions President David Stockin discusses Part 5 of a 5-part series about lightning strike scenarios and the ways to protect against them.

In the previous four episodes, we discussed the 4 lightning scenarios that cause damage: cloud-to-cloud strikes, nearby ground strikes, strike to incoming power lines, and finally direct strikes to your building.  These problems can be resolved with the following lightning protection strategies:  First, a Franklin-style lightning protection system with lightning rods on the roof of the building protects top of your building.  This system is tied to the building grounding system, which is made up of ground rods and possibly a buried ground ring.  Finally, surge protection device systems will protect your electrical system from incoming lightning surges on your incoming lines.  A cascaded surge protection system can add a second line of protection against surges to your electrical system.  These systems all work together to create a complete lightning protection system.

In this episode, E&S Grounding Solutions President David Stockin discusses Part 4 of a 5-part series about lightning strike scenarios and the ways to protect against them.

Direct lightning strikes are the fourth and least common scenario that can damage your building.  However, a direct lightning strike can be very powerful and cause major damage.  The odds of a direct strike to your building will depend on the lightning strike frequency in your area.  Due to the high currents, it can start fires in wood structures.  It will also cause a large electromagnetic field pulse.

In this episode, E&S Grounding Solutions President David Stockin discusses Part-3 of a 5-part series about lightning strike scenarios and the ways to protect against them.

Ground strikes are the second most common source of lightning damage, due to the direct coupling of ground currents traveling through the earth and into the concrete encased steel components of a structure.  These steel components will need to form there own magnetic fields which in turn will can cause damage to electronic systems within the structure.  Understanding how lightning can damage a structure is key to understanding how to protect a structure.

In this episode, E&S Grounding Solutions President David Stockin discusses Part-1 of a 5-part series about lightning strike scenarios and the ways to protect against them.

 Air-to-Air strikes are the most common source of lightning damage, due to electromagnetic fields (EMF) and the damage this interference causes to electronic systems.  Understanding how the EMF from lightning cause damage to your structures is key to understanding why the solutions work and how lightning protection systems work to protect you from numerous different scenarios.

E&S Grounding Solutions President David Stockin responds to viewers' questions about the differences between ground “loops” and ground “rings”. Ground loops are a common term that is often ill defined and even more often used inappropriately. Typically, ground loops are used to define a process where the return currents (neutral currents) are allowed to travel back to the source on the normally-non-current-carrying-exposed-conductive-parts of a circuit, in violation of NEC 250.6 –Objectionable Currents.  Objectionable Currents are hazardous to both persons and equipment and must be removed from any circuit.

In this episode, E&S Grounding Solutions President David Stockin responds to viewers questions about the dangers of Step Voltages. Step voltages are a very dangerous and unseen hazard. Primarily caused by lightning strikes or downed power lines, step voltages are large differences in potential that are a short distance from each other, which can turn the person or animal taking the step to become a conduit that the electrons use to flow from one potential to the other. David describes the dangers and explains the process by which this current flow occurs. He also offers some mitigation and safety tips.

In this episode, E&S Grounding Solutions President DavidStockin goes into detail on the importance of addressing your grounding system during the design process and how not doing so can cause costs to dramatically increase. David discusses the issues that can arise when grounding is an afterthought instead of a forethought and tells us a few of the details and standards that must be covered.

In this Episode of Ask the Grounding Experts, E&S Grounding Solutions President David Stockin discusses the Top 3 areas of improvement that are needed in Article 250, the Grounding Section, of the National Electrical Code (NEC).

In particular, the importance of installing a copper wire in branch circuits instead of using steel conduit is discussed.  In addition, the human safety reasons for always bonding the steel rebar in concrete (concrete encased electrodes) and the need to use copper in Liu of building steel for down conductors and grounding electrode conductors is also examined.  A few small adjustments to the National Electrical Code could help to dramatically reduce electrocutions, save lives, improve reliability, and reduce the costs of corrosion on our infrastructure.
